The wave described by {\y}=0.25 \sin (10 \pi {\x}- 2 \pi f ), where x and y are in metres and t in seconds, is a wave travelling along the -

Correct Answer is : + ve x direction with frequency 1Hz and wavelength λ=0.2m

+ ve x direction with frequency 1 {\Hz} and wavelength \lambda=0.2 {\m}

-ve {\x} direction with amplitude 0.25 {\m} and wavelength \lambda=0.2 {\m}

- ve x direction with frequency 1 {\Hz}

+ ve {\x} direction with frequency \pi {\Hz} and wavelength \lambda=0.2 {\m}
